a process or method of this particular character.

To the foregoing and other useful ends, the invention consists in the matters hereinafter set forth and claimed, and shown in the accompanying drawings, in which the single figure is a perspective of a mail box having a simulated oxidized surface produced in accordance with the principles of the invention.

The process or method comprises, for example, in the making of a mail box of the kind shown, the giving of the sheet-metal box a base coat of black enamel, whichmay be black japan, oil varnish enamel or pyroxylinienamel, this base coat being applied to the metal surface by dipping or spraying or brushing. This base coat is then baked hard, if such is required, and then afterward the black base coat is striped or spotted by applying. bronze powder mixed vwith bronze liquid, this bronze solution being preferably sprayed on to the black base :oat to produce spots or stripes resembling copper or bronze or brass in appearance.

Thereafter, if greater durability is desired, a film or coat of varnish or pyroxylin lacquer is sprayed over the entire article. As shown in the drawing, the result of such process or method will be dark stripes 1, if a striping effect is employed, alternating with the lighter stripes2 of copper or bronze, the stripes preferably fading into each other.

In this way, therefore, an imitation oxidized copper or other metal surfaceis produced, which is surprisingly handsome and efiective in appearance.

It will be understood that the metallic solution may be either actual metallic solution or imitation metallic solution, this being immaterial so long as the appearance of oxidized metal is produced. It will be understood, therefore, that in the claims the word metallic has this meaning, as it is immaterial whether metallic substances are actually employed in making the spraying solution, or whether imitation metallic materials are employed for this purpose.

Without disclaiming anything, and without prejudice to any novelty disclosed, what I claim as my invention is:

1. The method of producing an imitation oxidized metal surface, to provide an ornamental exterior simulating oxidized metal for any desired object, comprising the formation of a base coat of dark shade, and thereafter spraying a metallic solution on to the base coat in spots or stripes, leaving some of the base coat exposed, and with the exposed portions of the base coat and the metallic portions fading into each other, producing the appearance of an oxidized metal surface.

2. The said method as specified in claim 1, the said. base coat being black japan or any liquid that will produce a lustrous black surface, and the said metallic solution comprising bronze powder mixed with bronze liquid in such condition as to be easily sprayed upon the black surface.

3. As an article of manufacture, an object having the desired form and having an imitation oxidized metallic surfaceproviding an ornamental exterior simulating oxidized metal formed by a base coat of lustrous dark shade, with an upper metallic coat, leaving portions of the base coat exposed, and these exposed portions fading into the metallic portions of the'surface, producin the appearance of all-oxidized metal sur ace.

4. A structure as specified in claim 3 said base coat being black apan, or any liquid that will produce a lustrous black surface, and

'said second mentioned coat being a dried mixture of bronze powder and bronze li uid.
